Life cycle:The egg overwinters. I found the caterpillar in May 2011 (Northern Greece, Askio mountains, Quercus pubescens and on Olympus at Q. coccifera) and in May 2012 (Sardinia, Quercus ilex) to mostly sunny forest edges on lower branches of medium high oaks. It lives in total from April to early June.

The moths fly in the autumn from September to November.

Remarks: Dryobotodes carbonis is a close related vikariant of Dryobotodes roboris and unlike this distributed in the eastern Mediterranean (Greece to Italy, Asia Minor, Middle East). To the north, it is observes to Slovakia and southeastern Austria, to the west to Corsica, Sardinia and mainland France in the Alpes-Maritimes and the Var (where exists a contact zone with D. roboris).
